構が内蔵され、また桟木も多くなるため性能が低下し、
高遮音タイプのものでもＪＩＳに定める遮音等級Ｄ−４
０程度の遮音性能しか確保されていない。Generally, the partition panel has a double wall structure in which a sound absorbing material such as glass wool is inserted between front and back plates such as gypsum board and plywood, and the connecting portion is slid as shown in FIG. Therefore, a complicated mechanism such as the pantojack 50 is built in, and the number of berths increases, so the performance decreases,
Sound insulation class D-4 specified by JIS even for high sound insulation type
Only about 0 sound insulation performance is secured.

するものである。Further, the connecting portion with the wall surface or the like is generally constituted by a sliding cut-off frame formed of aluminum or the like and a packing or the like, and the elastic member such as the packing is improved to improve airtightness. Since the insulation frame is not designed for sound insulation, its performance is lower than that of the panel part, and it is generally D
It has a performance of -30 or less. In the pantojack, a partitioning panel is fixed by pressing a blocking frame against a wall surface or the like.
【０００５】このため、間仕切パネルと連結部分を合わ
